Why Conversational Language Outshines Formality in Public Speaking

Public speaking is an art form that has evolved dramatically over the years. From grand oratory in ancient Greece to TED Talks today, the delivery of spoken words has always been a tool to inspire, inform, and persuade. But in a world that values connection and authenticity more than ever, conversational language has emerged as the most powerful tool in a speaker's arsenal. Why? Because approachable, natural language builds trust, fosters connection, and leaves a lasting impression.

In this blog, we’ll explore why conversational language is superior to formality in public speaking. We’ll delve into the science of communication, unpack real-world examples, and offer practical advice to help you adopt a conversational tone in your speeches. So, let’s dive in.

The Pitfalls of Formal Language

Distance and Detachment

Formal language, often marked by rigid structures, complex vocabulary, and a polished tone, can unintentionally create a barrier between the speaker and the audience. When language feels rehearsed or overly polished, it can come across as insincere or inaccessible.

For example, imagine a corporate CEO delivering a speech to employees using phrases like, “In light of the forthcoming fiscal paradigm shifts…” instead of simply saying, “As we prepare for changes in our budget…” The former might sound intelligent, but it risks alienating listeners. Research published in the Journal of Business Communication found that using overly formal or complex language can reduce perceived credibility, as audiences tend to value clarity and relatability over sophistication.

Losing the Human Touch

Formality can also strip away the human element from communication. Audiences crave authenticity—they want to feel that the person speaking is relatable, not a distant figure delivering a lecture. Formal speeches often lack emotional resonance, making it harder for listeners to connect on a personal level.

The Power of Conversational Language

Conversational language, on the other hand, brings warmth, clarity, and relatability to public speaking. It mirrors the way people naturally talk, which makes it more engaging and memorable.

Relatability

When you use conversational language, you invite your audience into a dialogue. This approach makes your message feel personal and approachable. Consider the speeches of British educator Sir Ken Robinson, whose TED Talk Do Schools Kill Creativity? remains one of the most-watched talks of all time. Robinson’s use of humour, storytelling, and conversational language created an intimate atmosphere, even though he was speaking to millions.

Fostering Trust

Authenticity builds trust. A study published in the Journal of Public Speaking Research found that speakers who used conversational tones were rated as more trustworthy and approachable than those who relied on formal language. This is because conversational language signals honesty and openness, making audiences feel like they’re being spoken to, not at.

Clarity and Simplicity

Clarity is key to effective communication. Conversational language prioritises simple words and straightforward sentences, ensuring that audiences of all backgrounds can understand the message. For example, think of legendary British broadcaster David Attenborough. His documentaries use simple, vivid language to make complex ecological concepts accessible to everyone, from children to scientists.

Real-World Examples of Conversational Speakers

Brené Brown: Authentic Storytelling

Brené Brown, an American researcher and storyteller, is renowned for her conversational style. In her TED Talk The Power of Vulnerability, Brown uses self-deprecating humour, relatable anecdotes, and direct language to connect with her audience. Lines like, “I’m not a naturally empathetic person…” instantly disarm listeners and make her message more relatable.

Barack Obama: A Balance of Conversation and Gravitas

Former U.S. President Barack Obama’s speeches are a masterclass in combining conversational language with formality. He often begins with relatable anecdotes or rhetorical questions like, “How many of you remember your first job?” These moments humanise him before transitioning into more formal policy discussions.

British Examples: David Cameron and Boris Johnson

British politicians often vary in their use of conversational versus formal tones. David Cameron, for instance, was known for his polished yet conversational approach, often weaving in anecdotes and direct addresses to the public. Boris Johnson, by contrast, leans heavily on informal and humorous language, which resonates with certain audiences despite its divisiveness.

How Conversational Language Builds Connection and Trust

Engaging Tone

A conversational tone mimics natural dialogue, making the audience feel as though the speaker is talking with them rather than at them. This creates a sense of partnership and mutual respect.

Inclusive Language

Using inclusive phrases like “we,” “our,” and “you” fosters a sense of community. For example, saying, “We all know how it feels to face a challenge,” instantly draws listeners in and makes them feel part of the conversation.

Emotional Resonance

Conversational language taps into emotions more effectively than formality. Personal stories, light humour, and rhetorical questions create an emotional connection that formal speeches often lack. Science backs this up: a study in Frontiers in Psychology found that emotionally engaging speeches were more likely to be remembered and acted upon.

Practical Tips for Making Your Language More Conversational

1. Use Everyday Words

Avoid jargon, technical terms, or overly academic language. Instead, use words your audience would use in daily conversations.

2. Short Sentences and Pauses

Write and speak in short, digestible sentences. Incorporate pauses to mimic natural speech patterns and give your audience time to absorb your message.

3. Ask Questions

Rhetorical questions or direct queries keep your audience engaged. For example, “Have you ever felt nervous before a big presentation?” invites listeners to reflect and relate.

4. Inject Personality

Let your personality shine through. Use anecdotes, humour, and colloquial expressions to make your speech feel genuine.

5. Practice Reading Aloud

Rehearse your speech out loud to ensure it sounds natural. Reading silently doesn’t reveal awkward phrasing or overly complex sentences.

Balancing Conversational and Professional

Conversational language doesn’t mean sacrificing professionalism. The key is to find a balance that suits your audience and context. For instance, a keynote at a formal business conference might require a slightly more polished tone than a community workshop. Adjust your vocabulary, tone, and delivery style to align with the setting while maintaining warmth and approachability.

Conclusion

In a world where connection and authenticity reign supreme, conversational language is the secret weapon of effective public speaking. It builds trust, fosters relatability, and ensures your message is understood and remembered. Whether you’re addressing a boardroom, a lecture hall, or a community group, speaking in a way that feels natural and approachable will set you apart as a speaker who not only informs but inspires.

So, the next time you prepare a speech, remember: speak as if you’re having a conversation. Your audience will thank you for it.
